Beit lmown'that I, JULIUsBm-in,

Feuerbach-Stuttgart," Germany, uhave in yvented certain-i new `and useful Improvements -in Radiators, of which the following is a specification. y p My invention relates to radiators comprising interchangeable cooling elements, and'a'primary object isto provide an improved Vreadily 'detachable hollow coupling forconnecting the ends or terminals of the `cooling elements wi h the Vheaders of the radiator such that one sided tension is prevent-` ed frombeingset; up in the thin walls of the elementsand l'a firm connection is insured without the -walls being torn apart. v To this i lockedin position by one single screw or by the line means of the screw itself. v l

To this and other ends,.the inventionconsistsv in the construction, arrangement and combination of parts described hereinafter and pointed out in the claims. d Y

One form of my invention and modifications thereof are represented by way of example in the accompanying drawing,

wherein Figure 1 is a frontelevation of one form of my improved radiator,-some of the coolingV elements having been removed and lateral members being shown in section.

Fig. 2 is a lvertical cross-section taken on 2-2 in Fig. 1, and Fig. 3 is a vertical crosssection, enlarged, showing the improved connection of a cool; inv-element terminal with the header;

igs. 4 and 5 are like sectional views, enlarged, showing modifications of the connection shown in Fig. 3. Referring to the headers of the radiator and b recesses which are provided therein. l recesses b one continuous recess running from end to end of the header may be employed if desired. The headers or terminals c of the interchangeable tubes a7, having very thin walls, are fitted into said recesses b. The depth of the tubes d is preferably the same as that of the upper and.lower headers a, so that the front and rear faces of the a-.sublject of the German Emperor, and residentof "packing rings i and i.

tubes are flush withthose of the headers, as, f

shown inuFig. 2; The lheaders va Yare provided with lugs e which may be carried by 'i bars fof U-section. Thesebars arefmounted on the frame of the car and thus serveto connect the upper and lower headers a 'and toifsupport the radiator Vas a whole onthe I frame ofthe car. sible .to take the entirel radiator readily apart', sothat interchangeable members may be assembled, without employing any solder, merely by thenuse of screws.

. In .the construction vrepresented i a -pipe yg isscrewed intothe wall of the header a in one ofthe recesses `Consequently, it V.is pos-1 12,'saidV pipe.

`being provided with la number of openings 7L 1n its circumferencefor the passage of the A v cooling medium. A rubber ring i. is :first placed around the pipe g, andthen the terminale of the interchangeable'cooling element is yfitted upon Vsaid pipe by means of .its an? f nular memberlc; surrounding the pipe at theV Aopenings L andabutting against the rubber ringe: .The packing Vring i l1s thereuponA lplaced on the pipe gvan'd,

A At i l vided between the cooling elementandthe Y the same time electrical insulation is proemployed similarly header a. A plug Zis I the rings i and 11'` in as in Fig. 3 for locking position. A v v y v In the modification shown ink Fig. 5the same reference characters are employed asin Fig. V3 and 4 for similar parts. A flanged v intoV the wall f the upper-header a, its nanged end being located in the annular member la provided on the end of the interchangeable cooling element c.' A rubber tubular member g is screwedin' a recess b Y cooling packing ring z' is interposed at one side of the ring to form a yielding connection between the members/c andy.

The other side ofthe ring ,7c isvclosed by the plug Z screwed not into the tubular member as shown in F ig. 3, but directly into the ring surrounding the same. For the purpose or' electrically `insulating the ringY 7c s from the flange of the member g an addiandopeninginto one of the upper headers, Ythe other vof the upper headers having an annular member surrounding said tubular member, a` lower tubular member securely vcarried by and opening into one of the lower headers, the other of the lower headers 'having an annular member lsurrounding the lower said tubular member, and elastic packing'rmgs locked between each tubular member and :the adjacent vannular member for forming chambers inthe annular members,
